cHmNY-LUE CLEANER.

To all 'whom t may concern:

Be it known that I, WILLIAM H. PERRY,l a`

. kcitizen of the United States, residing in Concord, inthe county of Merrimack and State of. New Hampshire, have invented a new and yuseful Improvement in Chimney-Flue Clean-- 'Y ers, of which the following is a specification;

`This invention relates to an improved chimney-flue cleaner, adapted to be inserted from the upper end of the chimney; andit relates more particularly to the means whereby it is rendered expansible and conltractible in order that it may be ap licable to chimneys and chimney-flues of iferent sizes, and to .a peculiar construction whereby when it is dropped into a chimney it penetrates any mass or substance which has collarged detail in cross vertical section of one im Shoulder b is 35.

of the ,radial brushes. Fig. 4 is a horizontal l Similar letters of reference indicate correa represents a vertical rod pr ferably enlarged lat its lower portion whereby an annuproduced. The upper portion of this rod 1s provided with. a sleeve c whichis held a'djustably as. to height by a ,setscrew-c which extends-through the enlarged upper portion of the sleeve. The extreme upper end of the rod has screwed'to it an eye d whereby the ydevice may be suspended by a rope. The lower end of the rod a is rigid with a plate e, circular, or approxi- '-mately so,l and provided next its periphery with pairs of upwardly extending ears f.

The ears constituting each pair have pivotally secured to and between them at f the lower end of a flat bar g whose u per end is piotally,connected at g with a ar'h, said arsg and h c'onstitutinga jointed lever. A disk-shapedvplate k is `rilgid on thex lowerI end -of the sleevelc and is a' a ted when the setscrew c is loosened to sli e with said sleeve down on therod a as far as the shoulder b,

Y said. plate k being provided with peripheral andsubstantially radial-slots m in which the upper ends of the-levers g h are pivotally se-` Specification of Letters iatent.

clired at h.4 The .member g of the lever g h is flanked, as shown in Fig. 3, .by twoparallell portions which constitute a hollow brushback, saidportions consisting of the iiat rear portionl n and the portion n which receivesrows p of bristles, preferably made of wire, said rows being arran ed substantially radially. The brush-bac is secured to the o posite sides of the flat bar g in any suitab e manner, preferably by bolts r, see Fig. 2. Thus the brush-backs are arranged on substantially radial planes, and the bristles are on lines' which spreadv from the backs, so that when the cleaner i's closed, as in Fig. l, the bristles entirely 'surround the rod and operating mechanism. v

The lower Vplate or disk e constitutes the circular base of a downwardl extending conicalA plunger comprising saidI disk c and four radial wings s each of which is provided with a vertical and radial slot into which is bolted at -s a plunging knife t, said knives projecting beyond the outer edges of the Wings s and their edges being preferably sharpened. and parallel with said outer edges.

The outer edges of these knives therefore ex- I parts e, s and t reduces a cone-shaped plunger with radial y extending knives com- 1n to a point at their advancinfr ends.-

n operation, the brush-holder is` ex` panded from its closed position indicated in Fi 1 to an open position such asis indicated inig. 2, the de lree to which it is expanded being regulated to be inserted, an the limit of ex ansion being controlled by the shoulder .f After it has been properly expanded, the stop c may be set against the u per disk k and the dcvice'with a rope tie to its upper end at d isV dropped intothe chimney-Hue from the upper end. In 'case obstructions are met with, even if they wholly close the flue, the plunger with its 'radial and pointed knives uickly penetrates them and clears a space or the brushes behind it.y The fact that the device is necessarily somewhat heavy, being made of iron, 'causes its fall to be sullciently powerful for the conical end to penetrate any glass ofsoot which may be found in cl1in1ncy ues.h

In constructing these devices variations in the sise and length of the levers and in the radial or approximatelyradial positions of the slots m and ears f may be produced in the flue into which itis v order to render the shape of the brush when 'expanded to conform approximately to the shape and size of the Vflue in connection with which it is to be used.

Having thus fully described my invention,

rod, an upper disk adapted to slide on said rod, a series of jointed levers arranged around the rod and each pivotally connected at vits opposite ends to the upper and lower disks,

a series of hollow brush-hacks each consistmg of two parts bolted tothe opposite sides of the lower member or bar of a jointed lever,

and radially disposed bristles secured to the outer wall of each brush-back, for the purpose setvforth.

2. In an expansible chimney-flue cleaner, a' rod, eXpansible mechanism surrounding vsaid rod, brushes supported by said mechanism, a reversed cone-shaped plunger extending Jfrom the lower end vof the rod and compr1sing a base and a plurality of substantially radial wings, and knives or cutters supported by said wings and corresponding substantially inshape thereto with their lower ends meeting at a central point below the plunger,

'substantially as and for the purpose set forth. v In testimony whereorl I have signed my name to this specification in the presence lof two subscribing witnesses. l WILLIAM H. PERRY.
